I have a twitter account. I never found a use for it.
Now I have one. I will post there whatever interesting thing I find. Just right-click, "Post to Twitter" and voilá:
Here you can see the window, which is filled automatically with the post title and URL (made tiny, 140 chars is not much!), with the classic char countdown.
Also in the background, some news and my twitter account.
BTW: Uwe was awesome.
